//
//  Trantor T338 Definitions File
//
//  This file contains definitions specific to the logic used on the T338
//  parallel to scsi adapter.
//
//  Revisions:
//      02-01-92  KJB   First.
//      03-12-93  KJB   Now supports polling thru CardInterrupt and
//                      StartCommandInterrupt/FinishCommandInterrupt.
//      03-19-93  JAP   Implemented condition build FAR and NEAR pointers
//      03-25-93  JAP   Fixed up prototype typedef inconsistencies
//      05-14-93  KJB   Added CardParseCommandString for card specific
//                      standard string parsing across platforms.
//                      Changed CardCheckAdapter to accept an
//                      Initialization info from command line, ie
//                      force bi-directional ports, etc.
//                      All functions that used to take an PBASE_REGISTER
//                      parameter now take PWORKSPACE.  CardCheckAdapter
//                      takes the both a PINIT and a PWORKSPACE parameters.
